Hi all,
I have a PCB that uses a couple of SGTL5000 chips. I've built a few of them and they work.
I had one that had a mistake. I didn't notice it, but the 1.8V regulator for one of the SGTL5000 chips wasn't fully connected. I fixed it, but something is still wrong. It appears that something is pulling down the 3.3V output of the Teensy, and as a result things are not working correctly.
I guess I will try to remove that SGTL, but I'd love to know if anyone else has experienced damage to an SGTL5000 when the 1.8V supply was missing.
Thank you!
